7 Be it known thatz'HARnY 'EwHoi Nic, a

citizen ofithe United States of America,

' residing, at 'East Liverpool, in the county of I ColumbianaandState ofOhio, has invented new and useful Improvements in Insulator zfurthermore'to provide a bracket for the Brackets, gOf which the"following is a spec ification, p r I The-objec t' of the invention isto provide a bracket fo'r usefin supporting insulators forelectrical-wiring"and installation where& in all the parts including thescrew orscrew shankor other fastening means whereby attachment of thebracket to. a: supporting .ob-

indicated, purpose which may be constructed at a small-cost,without-resorting to castingor millLi-Wo'rk, and under conditions"insuring the requisite strength, stability and durability; and withthese eobjects. in view- 7 the invention consists in aic'onstruction andflco'mbination ofparts ofwhich a preferred 7 embodiment .is shown in theaccompanying drawings, wherein carries a threaded shank 12 and thelatter -plate. v e

i to the in: convergent relation jto -form' the side members 16' ofthebase while the terminal portions ofithe blank are arranged in paraleand are secured together by atransverse It is preferableparticularly asa means of economy in construction to employ a fastening 'shankor screw12-which is constructed separately from the bracket,- so

lelism vas indicated at 17 to form the stem that the best skill in screwconstruction may be utilized-therein without especial reference tobracket or other features-of the bracket in connection with which 'suchscrew may be used, andto this end a commerc al lag screw or cap screwis-employed "1n thls connection and the bearing portion of the baseofvthc bracket is provided with .fan' openings-1 9 through which theshank of the screw extends, the head 12" thereof resting uponthe'surface 'of saidbearing' portion 15 of the base. I I q c It isdesirable, however, thatithe bra'cket may be applied to thesupportingstructure in connection with which .it is to be; used,

or 'in other 'words'that the shank 12 may be screwed into suchsupporting object turning the bracket, as*'d isti-nguished from turningthe screw independently of the bracket, and to this =end there isemployed in connection with thefbracket' a wrench; plate 20 seated-onthe bottom or bearing por tion of thebasebetween the upturned con-Vergent portions thereof and provided "with aseat 21 of a size and shapeadapted to receive the head of the screw and hold it;

' against independent rotation. In the construction illustrated theendsof the wrench plate are interlocked Withithe base by provoiding the samewith terminal extensions 22 engaging openings or cut-awayi'portions 23atithe; junction of the bearing portion of the base with the upwardlyconvergent side 2 members thereof, as clearly shown in: Figure 1. It isalso desirable tovhold' the fastening screw against displacement ordisengagement of its/head from the seat 21, and therefore, as shown inthe drawing there is'employed a retainer 24 secured to and preferablyforming a reinforcement of the shank elements 17 of the main blank andde ending into such terminal relation head of the fastening screw as toprevent its removalfrom the seat, Deflection; of the free portion ofsaid retainer,
